Null Pointer Exception at startup

Hey, I understand this may not be an Iris issue, but I'm not a shader guy so any help to narrow it down is much appreciated. Here's the error that appears on client startup: 
[18:25:42] [Render thread/ERROR]: Failed to create shader rendering pipeline, disabling shaders!

True to its promise, joining a server shows no shaders, just vanilla graphics. I'm running on macOS, with the latest Distant Horizons mod for Fabric.

Try disabling the two Xaero's mods and Forge Config API Port (Xaero's dependency), see if it works.

It says loading 17 mods I think because the mods are still in the client, however they are all disabled except the ones you see in the lines below.

Ah, I think I know this one. Try updating Iris to version 1.8.11, if available. Sodium 0.6.13 made a change that causes Iris version 1.8.8 or lower to crash with similar message. See if updating fixes that.
